If it moves 4.5 times a year and each time it moves 10 meters, one one year it moves 45 meters. Now we want 11 years, so that's 45 times 11 which would give you 495 meters in 11 years

Feliz [49]

Answer:

15 goals out of 50 penalty kicks was scored by brock

Step-by-step explanation:

If Brock shoots 50 penalty kicks and the probability that he scores a penalty kick is 3/10, the number of goal brock is expected to make can be expressed as:

Number of goals scored = probability value * total penalty kicks taken

Number of goals scored = \frac{3}{10}*50

Number of goals scored = 15 goals

Bill has $2.00 in quarters and dimes. the number of quarters is 4 less than twice the number of dimes. find the number of coins
Dafna1 [17]
Define your variables:
Q: number of quarters
D: number of dimes

Next, create your equations
Q = 2D-4
25Q+10D=200

Because one variable (Q) is already written in terms of the other variable, D, you can already start solving with substitution.
25(2D-4)+10D=200
50D-100+10D=200
60D=300
D=5

Substitute D back into the other equation to find Q. 
Q=2D-4
Q=2(5)-4
Q=6

Substitute D and Q into the second equation to check.
25Q+10D=200
25(6)+10(5)=200
150+50=200

This works, so the answer is right! Bill has 6 quarters and 5 dimes.

Find how many times 10 seconds is in 2 minutes and 45 seconds (16 times) and then multiply that my 6 (96) Then find what half of 6 is to compensate for the leftover 5 seconds (Half of 10 - so therefore the remaining amount of cars will be half of 6) to get 99 cars.

Use the formula F = 1.8C + 32 to convert -10C into Fahrenheit
photoshop1234 [79]
Well since the value of C has been given to you, plug it into the equation.

F = 1.8(10) + 32
F = 18 +32
F = 50

The temperature in Fahrenheit would be 50 degrees.
